Why don't you at a minimum complete your undergrad degree- 4 year program- in some hard science that would ALLOW you to go to vet school, IF you so choose. You can ALWAYS decide not to go to vet school, and if you feel strongly, obtain your vet certificate then. At least after the end of 4 years you would have allowed yourself the opportunity to grow some, mature, think things through, etc. (I am NOT saying you are immature, A!).

But, 4 years can do alot. 4 years, in school, can help you learn other things, be exposed to other things, etc. You might find after 4 years you don't want vet school or vet tech certification. You will then be much better positioned for transitioning into the work force, or further education with a four year degree, not limited to doing vet tech, as you might be with a vet tech certificate, and still able to get into vet school if that is what you want.

If you are uncertain NOW, try to buy time (i.e., entering a 4 year program) that keeps your options open.

I know not everything thinks obtaining a degree is the end all/be all that I tend to think it is. I do know that not many people say, "Oh, heck, I am so mad I went to college, it was a waste of time for me".

Good luck. Growing up isn't easy, but, usually, it is fun.

And, btw, I was 29 when I finished law school, and can tell you, it wasn't the end of the world.
